Pneumatic devices: Pneumatic air press, omnimed power lifter, tank valves and a haussman pneumatic lab tool.

How do hydraulic systems work:
A hydraulic system is used in machines that need fluid power to make them work. The fluid power used for these machines is a high pressured liquid, called hydraulic liquid.

How do pneumatic systems work: A pneumatic system is a system that uses air pressure to move either a turbine or a cylinder to accomplish some work.

What are the major differences between hydraulic and pneumatic systems:
Pneumatic systems use compressed gas such as air or nitrogen to perform air process. Hydraulic system needs fluids such as water to work.
